Selling a bike in premium condition

I bought this bike in winter 2024 from Bike Connections, and I maintained it very well. The original price was 550 + USD, and I have installed several gears (including locks that prevent wheels from being stolen) and a premium lock worth 50+ USD. It's medium-sized. I am 5'9'' and this bike is good for 5'5'' to 5'11''.
